STET CLEAN - Portable LED-UVC device for stethoscope disinfection

UVC light is a type of ultraviolet radiation within the electromagnetic spectrum, with wavelengths between 100 and 280 nanometers. At a wavelength of 254 nm, UVC light is particularly effective at inactivating microorganisms like bacteria, viruses, mold, and spores. 

How it works:

UVC technology inactivates microorganisms through photodestruction of their DNA and RNA:

UVC light penetrates the cells of microorganisms, damaging their genetic material.

This prevents reproduction and renders the microorganisms harmless.

UVC disinfection is chemical-free and environmentally friendly, with decades of proven use for air, water, and surface disinfection across sanitary, industrial, and domestic applications.

At Light Progress, our solutions are designed for safe, controlled use, ensuring cleaner, healthier environments.

Our air purifiers combine two advanced technologies for effective air treatment:

UVC Disinfection

Air is drawn into the purifier and passes through a UVC disinfection chamber, where 254 nm UVC light eliminates microorganisms such as viruses, bacteria, and mold by inactivating their DNA/RNA, preventing proliferation.

Photocatalytic Filtration (TiOx)

A filter made of titanium dioxide (TiOx) activates a photocatalytic process when exposed to UVC light. This decomposes volatile organic compounds (VOCs)—the source of odors, pollutants, and allergens—transforming them into harmless substances like water vapor and carbon dioxide.

Key benefits:

Eliminates pathogens (viruses, bacteria, and mold).

Neutralizes odors and organic pollutants.

Ensures deep air purification without chemicals.

Ideal for both residential and professional settings, this technology improves air quality, ensuring a safer and healthier environment."-C rays (100-280 nm) have a strong germicidal effect and reach their maximum efficacy at the 265 nm wavelength. The germicidal effect of UV-C radiation covers bacteria, viruses, spores, fungi, moulds and mites; this is mainly due to the destructive effect of the UV-C rays on their DNA, which damage their reproductive system and prevent them from replicating.

Our UVC devices provide effective water disinfection by inactivating viruses, bacteria, mold, and algae without altering water quality.

How it works:

Water flows through a stainless-steel chamber, a reflective material that optimizes UVC light diffusion.

Internal diffusers regulate water flow, ensuring even exposure to UVC light (254 nm).

UVC light penetrates water particles, destroying the DNA/RNA of microorganisms, eliminating pathogens, and preventing their proliferation.

Applications:

Ideal for homes, schools, offices, medical facilities, sports centers, and other public/private environments, our devices deliver safe, pathogen-free water without chemicals, odors, or changes in taste.

Our UVC cabinets and boxes are designed to quickly and effectively sanitize various objects by eliminating microorganisms such as bacteria, viruses, and mold.

How it works:

High-intensity UVC light (254 nm) is uniformly emitted within the chamber, penetrating microorganisms' cells and disrupting their DNA/RNA, preventing reproduction and ensuring rapid inactivation.

Applications:

Professional tools: Medical, pharmaceutical, and dental instruments (e.g., scalpels, forceps).

Food contact items: Utensils like knives and cutting boards, critical for food safety.

Everyday objects: Phones, keys, glasses, masks, and electronic devices.

Key features:

Quick and effective sanitization (99.9% efficacy, laboratory tested).

Safe, controlled, and intuitive operation for professional and home use.
